Video dissemination protocols in urban vehicular ad hoc network: A performance evaluation study
Yang Li, Farahnaz Naeimipoor, Azzedine Boukerche · 2014
Video dissemination over vehicular networks is an attractive technology which supports many novel applications. However, it is a great challenge to analyse the performance of video dissemination protocols due to highly dynamic topology and stringent requirements of applications. In this paper, we evaluate five existing robust video dissemination protocols in urban scenarios. We evaluate three routing protocols and two error resilience protocols. We also modify the frame coding technique for better performance. The results, more specifically, show that only one of the three routing protocols fulfils the general quality requirements. As for the error resilient techniques, we find that our modified frame coding approach performs better than the original one in four aspects. The results also indicate that the video coding scheme guarantees reliable video qualities.
